Canaray 139373

Otherwise normal tooth 11

Tooth 11 appears otherwise normal. The existing obturation in the primary root canal system of this tooth appears centrally positioned and extends to the root apex, and there are no signs of periapical pathology. No signs of root perforation are evident, and a displaced fracture plane cannot be visualized radiographically.

2. External resorption on tooth 11P

There is a moderately well-defined region of external resorption located along the palatal aspect of the coronal third of the root of tooth 11, just apical to its cemento-enamel junction region. The resorption is located supracrestally, and extends from the external root surface to the obturated primary root canal system of this tooth.

1. Rarefying osteitis associated with accessory root on tooth 11D

Tooth 11 is an unusual morphologic variant with a small accessory root budding off the distal surface of the coronal third of its primary root. There is rarefying osteitis located periapical to this accessory root, and the contiguous buccal cortex appears partial dehiscence, which suggests the presence of a draining sinus tract. The incomplete obturation of the unusual root canal system of this tooth is the most likely source of the patient's symptoms.

3. Prominent vascular channel distopalatal to tooth 11

A prominent accessory neurovascular canal is evident along the distopalatal aspect of the alveolar process of site 11. The average diameter of this canal measures approximately 1 mm. Although this represents a variant of normal anatomy, direct implant placement through this neurovascular canal may increase the risk of intraoperative bleeding.

Generalized periodontal bone loss

There is generalized mild horizontal bone loss involving the imaged dentition.

4. Mucosal thickening in right maxillary sinus

The anterior recess of the right maxillary sinus is partially captured in this imaging volume, and its visible portion appears opacified. No further comments can be made based on this limited field of view.
